Monochromatization of synchrotron

The bandpass of the incoming radiation has already been considered in connection with the monochromatization of synchrotron radiation, Section 1.4, and the finite resolution of the electron spectrometer, introduced in Section 1.5 (equ. (1.49)), will be taken up again in Section 4.2.2. Therefore, only the level width rnconvolution procedures will be discussed. Finally, the results are applied to the quantitative analysis of the linewidth obtained for the Is photoline in neon. 

A XAS experiment involves the irradiation of a sample with a tuneable source of monochromatic X-rays, usually from a synchrotron facility (high brilliance). Third-generation synchrotrons have sufficient intensity to observe XAFS spectra up to 100 keV. Nevertheless, laboratory-scale XAFS spectroscopy is of importance, despite the vast availability of synchrotron beam time [305].

The last decade has seen the introduction of several new characterisation techniques which have been of major assistance in understanding the structure of monolayers at a molecular level. The most important of these has been the use of synchrotron radiation to obtain diffraction patterns from films at the air/water surface. In principle it would always have been possible to use X-rays for this purpose but the high intensity and highly monochromatic nature of the radiation from a synchrotron source has made this technique far easier to use. A selection of recent papers based on this technique is given [79-88], not all of which refer to simple fatty acids. The information available from such experiments is of two distinct kinds, though, in several studies, both kinds of information have been obtained.
